adz.so vs Google Keyword Planner

adz.so and Google Keyword Planner serve different stages of a Google Ads decision. adz.so is an audit-first workflow for examining an existing account, finding issues, and organizing human review. Google’s Keyword Planner documentation describes a planning tool for discovering keyword ideas and getting search-volume, bid, and cost estimates; Google also documents forecasts for keyword plans. Keyword research can inform a campaign, but it does not replace an audit of the account that will run it.

This comparison is educational and does not claim that adz.so is a keyword-discovery or forecasting product. It also does not treat Planner estimates as guarantees of clicks, conversions, revenue, or profit. Verify the account, market, language, budget, conversion definitions, and current Google Ads behavior before acting. For an account evidence baseline, use the free Google Ads audit for agencies.

Identify the question first

Use Keyword Planner when the question is “which terms might represent demand, and what could a plan look like?” Use an audit when the question is “is this existing account structured, tracked, targeted, and reported well enough to make a decision?” A new keyword list can be useful and still perform badly if the landing page, conversion path, location, budget, or measurement is wrong.

Write the planning and audit scope:

• product or service, market, language, location, and customer stage;
• account, campaigns, match types, negatives, landing pages, and conversion actions;
• date range, budget, bid strategy, seasonality, and business objective;
• CRM, calls, ecommerce, analytics, margin, or fulfillment evidence required;
• approval, privacy, policy, testing, and rollback requirements.

The tool choice follows the missing evidence. Planner can help shape demand hypotheses; an audit can test whether the account can evaluate those hypotheses honestly.

Compare planning signals with account evidence

Keyword Planner can provide ideas, historical search estimates, bid or cost information, and forecasts for a selected plan. The numbers are planning signals subject to settings, geography, language, competition, seasonality, budget, and changing demand. They do not identify whether a particular query will become a qualified lead or profitable order.

An adz.so audit looks at the account that is already configured. It should be judged by whether it exposes findings with a clear scope, source, likely impact, uncertainty, and verification condition. It is not a substitute for deciding which products or services have demand.

Use both when appropriate: use Planner to form a demand hypothesis, then use the audit and controlled campaign test to assess whether the account can turn that hypothesis into a measurable business result.

Keep estimates and observed performance separate

A planning estimate is not an observed account metric. Before comparing Planner with an audit, label each field as one of the following:

• planned: a forecast or estimate based on selected settings;
• observed: a platform result from a defined account and period;
• joined: a business result matched from CRM, commerce, calls, or finance;
• modeled: a value produced by an assumption rather than a direct event;
• unknown: a field that is missing, late, contradictory, or outside scope.

For every decision, record:

1. location, language, network, device, seasonality, and plan settings;
2. campaign, match-type, negative-keyword, budget, and landing-page context;
3. conversion action, counting rule, attribution, and data maturity;
4. source for search volume, cost, clicks, conversions, and value;
5. CRM qualification, order status, refunds, margin, and fulfillment assumptions;
6. the reviewer responsible for deciding whether the hypothesis should be tested.

If a forecast says a plan could receive a certain volume, do not promise that outcome. If an audit finds missing conversion evidence, do not solve that uncertainty with a higher search-volume estimate.

Build a small testable plan

Select a limited set of terms that represent distinct intent, not every suggestion. For each term, write the matching ad, landing page, negative rule, conversion action, budget boundary, and success condition. Keep brand, category, competitor, research, support, and existing-customer intent separate when their business value or message differs.

Audit the campaign that Planner informed

After using Planner, inspect the implementation rather than assuming the plan is ready. Check whether campaigns separate markets, products, sales motions, languages, and budgets for a defensible reason. Review match types, negative keywords, search terms, location settings, schedules, devices, audiences, ad assets, landing pages, and conversion actions.

Use an implementation record:

An audit finding may reveal that an existing campaign cannot cleanly answer the Planner hypothesis because of mixed intent, broken tracking, or an unsuitable page. Fix the measurement and structure before judging keyword demand.

Watch for common planning errors

High search volume is not the same as high commercial value. A broad term can mix research, job seeking, support, supplier, and purchase intent. A low-volume term can be valuable if it represents a qualified niche. A low estimated cost can reflect weak demand, limited competition, or a mismatch rather than a bargain.

Common errors include:

• using a website seed without reviewing the language or intent of the ideas;
• treating grouped estimates as if they were guaranteed for one campaign;
• mixing locations, currencies, languages, or customer stages;
• adding every suggestion without a negative-keyword or landing-page plan;
• judging a forecast by clicks while the business needs qualified opportunities;
• changing several budgets, bids, pages, and conversion actions at once;
• leaving conversion definitions or downstream lead quality unresolved.

The remedy is a narrower hypothesis and a recorded decision rule. If the terms do not map to an offer, page, and measurable outcome, do not force them into the account because the planner produced them.

Run a fair evaluation

Use Keyword Planner to create a documented plan for one product, market, and intent group. Use an adz.so audit to review the existing account or landing path that would carry the test. Then compare the plan with observed data after a defined, mature period—not with an unverified promise.

Measure:

1. relevance of ideas to the actual offer;
2. clarity of location, language, budget, and forecast settings;
3. time to map terms to campaigns, negatives, ads, pages, and conversions;
4. tracking and data-quality issues found before launch;
5. search-term and query behavior after launch;
6. qualified lead, order, revenue, refund, or margin evidence;
7. decisions to expand, narrow, pause, or revise the hypothesis.

Do not select a tool because it produces more keywords or more findings. Select the workflow that makes the next test clear and keeps estimates distinguishable from evidence.

Which should you choose?

Choose Keyword Planner when you need keyword ideas, historical estimates, bid or cost context, or a forecast for a proposed plan. Choose adz.so when you need to inspect an existing Google Ads account and prioritize issues in structure, targeting, tracking, pages, or reporting. Use both when planning and account review are separate stages of the same controlled decision.

Before launch, verify the current Google Ads settings, policy requirements, conversion actions, consent, landing-page experience, negative-keyword plan, and budget approval. Start with the free Google Ads audit for agencies when you need to establish whether the existing account can measure the planned test honestly.
